Abstract The objective of this research is to investigate the performance increase of evacuated solar collector with Nano fluid. Solar collector includes absorber unit in order to transfer the heat energy to a working fluid. In this research it was intended to evaluate performance considering with Nano fluid. Improving the heat collection efficiency, efficient extraction of the heat from the solar collector, controlling the operating temperature, long maintenance free life of the device are some of the major challenges in collecting and extracting heat from the evacuated solar collectors. Using Nano fluids as working fluids are interesting and challenging. Improvement in the performance of the evacuated heat pipe was obtained using heat transporting Nano fluid consisting of aqueous dispersion (3 weight %) of copper oxide (CuO) nanoparticles; in comparison with the device without utilizing the Nano fluid.From the past research, Authors have analysed the performance with numerous trials. The result shows that evacuated tube heat pipe collector with Nano fluid give the better result than heat pipe collector without Nano fluid.

Biometric technologies provide consumers with a long-awaited convenience to securely enter cyberspace on the front end. The biometric open protocol standard (BOPS), developed by Hoyos Labs, protects digital assets and digital identities on the backend. BOPS is a biometrics-agnostic standard that opens an application programing interface (API) for registered developers. Entering as a game-changer, BOPS communication architecture enables two-way secure sockets layer (SSL) or transport layer security (TLS) connection over the encryption mechanism to the server, which employs an intrusion detection system (IDS). The IDS is an external system responsible for blacklisting devices that are violating the replay portion of this specification.

Fabrication and measurement of conformal aerodynamic windows and domes to precise optical tolerances from ceramic materials remains a problem. This paper describes the development of the Interferometric Tomography inspection system, based on a new method for wavefront and surface metrology on optics with very high aberrations. The metrology system is a modular attachment for integrating a standard commercial interferometer with an existing optical fabrication tool. The system will enable high precision measurement of infrared windows and domes in the process of their fabrication, until finished to specification. The capability for fabrication and metrology of aggressively aspheric optics, aberrated by design, will enable new optical designs of higher performance and lower cost, compared to existing optics.

Automated computer-aided procedure for component selection, optical design, and optimization was developed and used to produce prototype ocular optics of a head-mounted display for biomedical imaging, with the field of view and resolution approaching those of normal human vision. The new display has the potential to dramatically increase the amount and fidelity of real-time visual information presented to the user. The selected approach was based on a tiled configuration and "optically stitched" virtual image, resulting in seamless imagery generated by multiple micro-displays. Several optical configurations were studied in the design stage, to arrive at the optimal optical layout. The automated procedure provided for extensive search of the best candidate stock components out of thousands of candidate lenses offered by different vendors. At each iteration, the candidate lens was "digitally inserted" in the optical layout, its position was optimized, and the achieved merit function characterizing the quality of the stitched image was stored, along with the design prescription. A few best designs were then closely evaluated in a traditional "manual" procedure. The design effort was followed by experimental demonstration and tests of a limited prototype optical system.

We describe methods used to specify and instantiate hundreds of heterogeneous agents and their use in a simulation of national trade and shipping. The agents, representing synthetic corporate entities, interacted to produce hundreds of thousands of trade transaction documents. The goal for the system was for the corpus of documents to evidence diverse, but realistic linkage patterns of corporate entities engaged in emergent shipping behaviors. We then used the documents to test and evaluate a data mining tool that purported to be able to detect these types of behavioral patterns. Our contributions include a design algorithm for a heterogeneous MAS that produces multi-featured outcomes, and a method for instantiating realistic heritages and preferences of agents that extends recent work in heterogeneous random utility modeling.
